* - MUST set `offer_node_id` to the node's public key to request the invoice from.
* - MUST set `offer_description` to a complete description of the purpose
* of the payment.
* - if the chain for the invoice is not solely bitcoin:
* - MUST specify `offer_chains` the offer is valid for.
* - otherwise:
* - MAY omit `offer_chains`, implying that bitcoin is only chain.
* - if a specific minimum `offer_amount` is required for successful payment:
* - MUST set `offer_amount` to the amount expected (per item).
* - if the currency for `offer_amount` is that of all entries in `chains`:
* - MUST specify `amount` in multiples of the minimum lightning-payable unit
* (e.g. milli-satoshis for bitcoin).
* - otherwise:
* - MUST specify `offer_currency` `iso4217` as an ISO 4712 three-letter code.
* - MUST specify `offer_amount` in the currency unit adjusted by the ISO 4712
* exponent (e.g. USD cents).
* - otherwise:
* - MUST NOT set `offer_amount`
* - MUST NOT set `offer_currency`
* - MAY set `offer_metadata` for its own use.
* - if it supports bolt12 offer features:
* - MUST set `offer_features`.`features` to the bitmap of bolt12 features.
* - if the offer expires:
* - MUST set `offer_absolute_expiry` `seconds_from_epoch` to the number of seconds
* after midnight 1 January 1970, UTC that invoice_request should not be
* attempted.
* - if it is connected only by private channels:
* - MUST include `offer_paths` containing one or more paths to the node from
* publicly reachable nodes.
* - otherwise:
* - MAY include `offer_paths`.
* - if it includes `offer_paths`:
* - SHOULD ignore any invoice_request which does not use the path.
* - if it sets `offer_issuer`:
* - SHOULD set it to identify the issuer of the invoice clearly.
* - if it includes a domain name:
* - SHOULD begin it with either user@domain or domain
* - MAY follow with a space and more text
* - if it can supply more than one item for a single invoice:
* - if the maximum quantity is known:
* - MUST set that maximum in `offer_quantity_max`.
* - MUST NOT set `offer_quantity_max` to 0.
* - otherwise:
* - MUST set `offer_quantity_max` to 0.
* - otherwise:
* - MUST NOT set `offer_quantity_max`.
